CALCULATING MACHINE.

Application filed October 21, 1922. Serial No. 595.925.

T 0 all whom it may concern:

Be it known that I. An'riiuu F. Poona, citizen of the United States.v and resident of Pelham Manor, in the county of \Yestchester and State of Nev York, have invented certain new and useful Improvements in Calculating Machines, of which the following is a specification This invention relates to calculating machines and it has for its object to provide certain improvements in that class of machines. One of the principal objects of the invention is to provide, in a calculating machine in which the register wheels are operated or controlled by a series of denominational racks, for a positively acting transfer mechanism capable of acting while the register Wheels are in gear with said racks and capable of acting in both directions for plus and minus calculations, and is in the nature of an improvement on the transfer mechanism disclosed in the application of R. H. Strother, filed August 21, 1922, Serial No. 583391. i

Another object is to provide a registering unit or totalizer of the sort just referred to and which is also of such kind that a plurality of such totalizers can, if desired, be arranged along a st of elongated racks so that the same racks can be used for registering in different 'totalizers or registers.

The invention also has other objects which will appear in the course of the following description.

To the above ends the invention consists in certain features of construction and combinations and arrangements of parts, all of which will be fully set forth herein and particularly pointed out in the claims.

- Some of the features of the invention are of such charactr that they can be modified considerably One embodiment of the in vention is illustrated in the accompanying drawings in which Figure 1 is a front to rear vertical section through the machine about on the line l1 of Figure 2.

Figure 1 is a continuation of Figure 1 toward the right, the rear part of the machine being broken away in said Figure Figure 2 is a plan view in section on line 2-2 of Figure 1.

Figure 3 is a front elevation oi the upper part of the totalizer. most of the figure being in s'ction-on the line 3 of Figure 1, the section extending to the bottom of the carrying wheels 36.

Figure 4 is a right-hand side elevation on a smaller scale than the other drawings.

Figure 5 is a transverse section through the swinging part of the register on' the line 55 of Figure l and looking toward the rear.

Figure 6 is an isometric view of a portion of the transfer mechanism.

The present invention relates chiefly to the totalizer or registering mechanism and the transfer mechanism, and the actuating nrchanism has therefore been shown only in a very much simplified form. It. will be understood that said actuating mechanism may be elaborated and the racks extended to accommodate a number of registers, only one of which is shown in the drawing.

Theframe or support for said actuating mechanism comprises a base block 10 having cut inzits upper face grooves 11 in which rack bars 12 are arranged to slide front and back. Said rack bars are the devices which actuate theregister in the sense that they drive the register'wheels, and they are also the devices which control the register in the sense that they determine the extent to which said wheels turn, and, therefore, the number that shall be registered on said wheels.- ,Other forms of actuating devices and controlling devices may be employed.

In the present instance these rack bars are shown only long enough to actuate one register but said bars may be made longer if de sired so that a. plurality of independent registers can be operated by them, said registers being arranged one in front of another along the racks. Any suitable means can be provided for imparting differential motion to these rack bars, such means having been designed in a great variety of forms well known in the art. In the present instance each of them is merly shown-with a handle 13 projecting-upward from its forward end through a slot 14 in a cover plate 15, which cover plate is secured as b y screws 19 to the base block 10. Each handle 13 may have a pointer 16 bent oli therefrom and co-operating with a series of graduations 17 suitably numbered. The machine shown being arrang'edtor decimal calculation these graduations are numbered from 0"? to '9, inclusive; The racks are restorectto' and flormally held in" their rear' positions by means of springs 18, each lrooked=into,t he rear end of a rack bar and said springsvat their .rear

ends being connected to a cross bar20 suit.

ably supported in arms of sheet metal frame pieces 21, which frame pieces are secured by H) rear ends of the slots 14 or by stops 23 provided for the purpose. The racks 12 are drawn forward by hand by manipulating the handles 13 to any desired extent to represent the digits of a number to be regis- 15 tered, and they are temporarily retained in their forward positions by any suitable means, that here shown consisting of a series of pawls 2i pivoted on a shaft 25 and pressed upward by springs 26 into engagement with a series of ratchet. teeth 27 on the under side of the several racks. In order to accommodate this pawl mechanism the block :has a transverse cut-out 28 in the underside thereof, which cut-out maybe covered by means of a plate 30 extending across the bottom of the cut-out and bent up at its ends and secured to the block 10 by means of screws 31, Fig. 4. The shaft is journaledin the upstanding ends of 'this plate and the ,springsw26bear against thehonizontal part of the plate. In order to release the pawls when it is desired that the-racks be restored bytheir springs 18,-.each of:said-. awls is in'ade with a dependingiar'm- 29. an'd a yoke or Jbail bar 32, mounted in arms 33 fixed on r the shaft-25,Textends=across said depending arms sodahat if saidshaftzbenrocked;clockwise in Figs: l'and' of--:the :pawls-will be depressed to release-.tlieraclsbarswThe shaft 25 projects at one end beyond the plate 30-and has a hand crank 34 thereon by means of iwhich it can be operatediwhenever .de- -:sired.-.

16." -Y-"'I-he registering and tranSferringinechaenisin actuated by the racks=12 comprises in Zeach. denomination a transmitting gear or pinion 35 which inthe present I instance -,1neshes-directly with the rack.12;' a carry- ;ingigea-ri36 meshing with the -pinion 35 on the sidethereof opposite to the rack 12; an idler pinion 37 driven bythe carrying gear -36-;:;and;;;the pinion 38' ofa dial wheel-40, said -pinioii driven by said gear 37; and also a so called Geneva wheel 41 driven by said carrying gear 36.

-It; may a iduin reading the drawing to say at the outset that gear 36 is hidden in Fig.

Lbyacertain gear 58 having the same peripheral: outline,- said':geani58=n1eshing with certain sector teeth 57. Parts 57. and 58 will be described hereinafter. '7

The wheels 36 are strung along a shaft a the wheels 37 along a shaft-43 and the dials 40 along a shaft 4-1 all of said shafts being: supported at their ends in a register frame 45 comprising side plates 46 secured together partly by the shafts referred to and partly by other frame rods, two of which have been numb-cred 47 on the drawing. These rods may be secured. in said frame plates by means of screws which for the purnose of identification have been designated by the same numbers as the respectin shafts and rods. The side plates 46 at their lower rear corners are pivoted by means of a rod or shaft 48 in the stationary frame plates 21, so that the frame 45 may be rocked about said pivot to lift the gears 36 out of mesh with the gears 35 in order in each calculation to have the registerlwheels disconnected from the rack during the motion of said'racks in one direction as is well understood in calculating machinery. By a modification of the mechanism this'disconnection could be effected between the-racks themselves and the pinions 35 but in the present instance I have preferred to effect it between said -pinions 35 and the gears 36.

:In order .to limit'thedownward movement of the register frame 45- each of the side on a portion of the base framework;

In the resent simplified actuating moi-ha I nism, the frame 455s'raised-andlowered by hand. Said frame-may and preferably does have. a cover plate'whicnhowever is not shown in the'drawi-ng.=;

The transfer. or carry-from :one denomination to another is=eifectedbymov1ng or displacmg the axis'bf oneof the pinions in 3tbe-'plane"o?E said pinion and in a direction contrary to that of the motion of the rail: 12. When thisis donethe pinion-35 pivot-s on said rack 12 so=thatthe1tooth at the upper side of the pinion which is in engagement with the wheel 36 moves twice as far as the axis of the" wheel To this: end

each of said wheels except the-one .of

lowest order is mounted on an individually movable support 51, Figs. 1, 5 and 6-, the wheel being journaled on a stud 52 riveted in and projecting leftward from said support. The support :51*is pivoted at itslower end on a stud 53 projecting leftward from a frame, bracket or.hanger 54, said hangers and the lower ends of said movable supports lying between the ranks 12 as shown. The series of brackets 54 are here shown mounted on a pair of frame rods 55 secured at their ends in the frame pieces 21, the brackets being spaced apart by washers 56. In the machine from which the present drawings were made the numerals are so loo r s) and its disposed on the dials that when the register is in gear, motion 'of the tacks-1'2 toward the front of the machine causes subtraction and motion of said racks towards the rear causes addition. If during the process of addition one of the supports 51 be swmr'. about its pivot 53 toward the front of the machine, that is to say, in a direction contrary to that of the motion of the rack 12 for addition the bearing will be moved a half space forward and the upper part of the wheel 35 will be moved one space forward and will therefore add one on the :arrying wheel 36 to which it is geared: and this will occur whether the rack 120i higherdenomination stationary at the time or whether it is in motion. If during the process ofsubtraction it is necessary to carry or transfer to one of; theregister wheels this is effected by moving the support 51in the opposite direction, namely, toward the'rearh 7 an order positively'fto .operate'- the supportsof any denomination fromthe carrying wheel' 36 of the :nez'rt lower denomination variouszdev-ices can; be provided' In fact? this function" oan be performed by mechanism in quite awariety of .forms of which that showli inth drawing is one instance; As showii'reoliofssaid supports is relonged upward and Z formed with I three teeth--57 atitsiupper'end, sothat said support is in 'theforin of asegmiit gear or se tor. a1=Said teethfmeslhwithrgear wheels 58 journaled' on the shait 42 inlalternationwith the carrying gears}, 36. r'Sa-id'gears 58 are'ot the: same diameter? and have ithe same number: of teeth as said gears 36; both-=- being thirty toothed-1% geazrsvro'lhis being". so,- the teeth=57= of theisegmentalzsupport 51-, have their pitch line tangent to those of: the gears amma 36; and the auis' of thepivot 53*is in the pitch lin8"0f='itl1e racks 12.-- These proportions canyof fcourse, 'be; varied, 1;;

I, i It ma be 'wfsufioientdescription-wot the wheels 36, 37; 38, wand-4i: to say that inthe specific machinepfromwhich the drawings were made these ;=parts are identical with parts occupying somewhat similar positions in the Wahl calculating mechanism constituting; partof the-fwell kn'own Remington accounting machine, which has for a number of'years-been inextensivea-uset Each of the carryingg'ears-36 is made in three planes or strata,- the*righthand one of which is an ordinarythii'tyatoothed gear; the middle plane has but three" teeth shown in dotted lines in Fig. liand' adapted every time the 'carrying' gear passesthe space between its 0- position to engagea ten toothedapinioir6l Fig. '5, constituting the right-hand plane/of one of the- Geneva wheels fl; The left-hand plane orlayerof the-qwheel 36 is of less diameter than the other two and is of cylindrical form-except described exceit to l that opposite each of the teeth 60 of said layer or plane has a peripheral. depression or cut-out. 62, Fig. l. The Geneva. wheel has a large scalloped part which normally rides on the smooth part 6 of this sec! ion and which is thereby locked against. rotation, but rotation of said (icneva wheel to the extent of one tooth is permitted by lhe cut-out 6. every time one of the transfer teeth 60 engages a tooth of the pinion 61. This form of intermittent gearing is so well known in the art that it need not be further say that the (ioneva wheel 41 has also a ie't't-band plane or stratinn 64 consisting oi a ten toothed pinion which in the \Yahl mechanism engages the thirty toothed part of the next higher carrying wheel 36. In the present mach ne this section of the Geneva wheel engages the gear 58, which gear at its lower side meshes with the support 51 of next higher denomination. The construction is such that when any wheel 36 passes from 9 to '0 or from 0 to 9 it turns the Geneva wheel one tooth space which turns the next succeeding gear 58 one tooth space inthe same direction that the carrying wheel 36 is turning: and said gear 58 rocks the support 51 of the next succeeding denomination one tooth space in the same direction that thecarrying wheel is turning and thus transfers to said next denomination, as described.

The Geneva wheels 41- may be mounted on. a transverse rod or shaft the same as the other pinions but as it is important that these pinions engage the carrying wheels 36 with considerable accuracy-theyare preferably mounted on individual adjustable supports 65. each of which has a stud 66 pro jecting therefrom on whicha Geneva pinion is journaled; Said supports consistof arms having hubs mounted on transverse rod 67 suitably secured in the side plates 46 ot' the, pivoted register frame 45. Each of said arms projects upward beyond -its pinion. its upper part lying between two adjusting screws 63, which screws are threaded through transverse frame bars 70, the ends of which are mortised into the side .plates 46. By adjusting these screws each Geneva pinion can be brought with precision into engagement with its carrying wheeli One of the bars 70 may have a slotted flange 71 to guide the supports 65 right and-left. Springs 72 are shown each drawing the upper end of one ot'thc supports 51 toward the front of the machine. These: are 110],- essential but are convenient in the process of adjustment, enabling the rear screw 68 to be left loose while the adjustn'ient is being effected by the forward screw against which the spring keeps the support constantly pressed. After the adjustment is made the. rear screw can be brought up snug to retain the support positively in place.

After a registering operation, it is necessary to restore the supports 51 to normal position. In the present instance said supports have a. normal middle position from which they are displaced toward the front of the machine for addition and toward the rear of the machine for subtraction. Each of said supports has a forwardly projecting arm having therein a V-shaped notch 73, the bottom of said notch being made with straight sides to receive a transverse bail rod '74 which is mounted at its ends on arms pivoted at 76 to the base-block 10. This bail is adapted to be swung forward to an inoperative position shown by full lines in Fig. 1 and backward to an operative position shown by dotted lines. In operative position said rod occupies the straight-walled bottoms of all of the V-notches 73 and accurately locates all of the supports 51 in their normal middle position. In Fig. 1 these supports are shown in such normal middle position in full lines but one of--them is shown by broken lines LI'OCkBd forward for additive transfer. \Vhether the support was rocked forward in addition or rearward in substraction the bail 74 would center it. This operation of restoring the transfer supports 51 is of course effected while the frame 45 is in its upper or inoperative position and the carrying gears '36 are out of gear with the pinions 35 and the gears 58 out of mesh with the segments 51, 57. Any suitable means can be provided for swinging the bail 74 at the proper time. In the simplified form of actuating mechanism shown in the present case one or both of the arms 75 is provided with a finger piece or handle 77 by which the bail can be worked at the proper time manually.

In the present machine the register wheel of lowest order is never actuated by transfer and it is therefore unnecessary that its pinion 35 be mounted on a movable support. I n this machine therefore the stud 52 for the right-hand pinion 35 is secured not in a movable support but in a special hanger 78, Figs. 4 and 5, secured on the same rods 55 as the brackets 54. It is this stationary hanger 78 which serves as a stop for the right-hand foot 50 of the register frame 45. It will be noted, however, that in all denominations that are receptive to transfer the wheels 35 are mounted on movable supports.

In the form in which the invention is here shown the studs 53 on which the supports 51 are pivoted, have no heads, said supports being simply set on the projecting studs and motion leftward off of each stud being prevented by the devices to the left of said support. At the extreme left-hand end of the system there is a bracket 80 similar to the bracket 78 and having riveted thereto a washer 81, Fig. 5, which ultimately prevents leftward motion of the last one of the supports 51. Each of the studs 52 has an enlarged head 32 and it is this head of the last stud to the .left which abuts against the washer 81,. Figs. 2 and 5.

The general mode of operation of the machine will be understood from what has been said, but this may be said additionally :If it is desired to add a number on the register, the frame 45 is first rocked to the position shown in broken lines in Fig. 4 to disconnect the gears 36 from the gears 35. The rack finger-pieces 13 are then drawn forward each to an extent depending on the digit to be added in that particular denomination, and the racks are held forward by the pawls 24. The frame 45 is then depressed to its operative position shown in Fig. 1 and the bail 74 is drawn forward to its inoperative position shown by full lines in said figure. The hand crank 34 is then operated to release all of the pawls 24 to allow the racks-12 to be drawn back to normal po sitiomby their springs 18. In this operation the register wheels areturned additively each to an extent depending on the initial forward setting of its rack 12.

In case any carrying wheel 36 passes from its 9 to its 0 position it will impart rotation counter-clockwise to a Genevawheel 41 which will rotate the gear 58 to the left of .said carrying wheel" clockwise one tooth. This gear will rock the'support 51 of the next higher denomination one tooth toward the 'frontiofthe machine'to the position "indicated in broken lines in Fig. 1, and thiszoperation willimpart an increment of motion to the next carrier wheel 36 equal to one tooth of'said wheel. After the registering operation is completed the operator will again rock the frame 45 to its disconnecting position and will then swing the bail 74 to its rear position, thus restoring any supports 51 and pinions 35 that may have been displacedi The machine is then readyfor another operation.

In case it is desired to subtract a number the frame 45 is depressed-to its operative position shown in Fig. 1, the bail 74 is drawn forwarduto its'inoperative position. and the several racks 12- are then: operated manually by their finger pieces 13 each to the appropriate extent. This at once-turns the register wheels in directions the opposite of those that they turnedyin the? case of addition. In case of transfer the Geneva wheels 41 and wheels'58 are'also turned in the opposite directionsrfrom those of addition with the result that the appropriate support or supports 51 are rocked rearward with the same result as inaddition but in the opposite direction." After the number has been subtracted the frame 45 is raised to its disconnecting position, the bail 74 is' moved rearward to restore any displaced transfer supports and the hand crank 34 is operated to release all of the racks 12 and to allow them to return idly to normal position under the influence of springs 18.

It will be noted that each of the gears 35, in the form of the invention shown, rocks back and forth from and to a definite normal position so that, if this gear were of greater diameter than here shown, it need not have a complete set of teeth extending clear around it. This gear is in the nature of a lever which, when registering a digit, acts as a lever of the first order and which, when transferring, acts as a lever of the third order.

In this form of positive transfer mechanism. as in all transfer mechanisms that operate byintermittent gearing, there is a certain amount of lost motion, with the result that in case it is necessary to tranfer through a number of wheels at a time as through a long row of nines in addition or of zeroes in subtraction, the wheels of higher order will lag, producing what has become known as a spiral in the transfer mechanism. It is therefore desirable to provide means for aligning the wheels after each registering operation. In the present instance the spiral would show not only on v the register wheelsbut also, on thepivoted supports 51, the first of which. in 2.. ion

carry would be approximately fully operate the next one not quite so fully, operated, the third a little more out of correct position,

* and so on.

Means can be provided in a variety of forms for aligning or removing the spiral from these parts. In this machine if the pivoted supports 51 be trued up that will of itself bring position. Two forms of aligning or spiral removing mechanism are shown in the present machine, one being spring operated and the other positively operated. Of these the positive operation is preferred for the reason that it is considered to be more'reliable.

The positively acting aligning or spiral removing mechanism shown in the drawing comprises a series of pointed or beveled plungers 83 mounted for up and down sliding motion in suitable holes in two frame bars 84 mounted one above the other above the wheels 36 and 58. Each of said lungers has a pointed lower end adapte to be pressed down into an interdental space in one of said gears 58 as shown in Figs. 1 and to true up the said gear exactly to its cor rect position. As shown in Fig. 3 each of these plungers not only engages a gear 58 but it also engages the thirty-toothed part of the wheel 36 next to the left of said gear 58 and which is-turned by a turning of said gear 58. The engagement of these plungers with both the gears 36 and 58 is not essential, however, as the mechanism would be the register wheels to correct lined up well enough by merely truing up either one of said sets of gearsrbut it is useful because by that means said plungers not only serve as spiral removing devices but they also serve as locksv for the registering gear train when the register frame is in its elevated position.

Any suitable means can be provided for elevating the plungers 83 to unlock the registering mechanism and for depressing said plungers successively beginning at the righ. hand end of the series. The means shown in the drawing for this purposecomprises a shaft 85 having spirally arranged eccentric parts engaging the plungers 83. In the preent instance, these parts are produced by providing a spiral rib 86, projecting from the shaft, 85, said shaft and rib passing through openings in said plungers to provide room for which openings said plungers.

are widened front and back as shown in Fig. 1.

In said Fig. 1 the plungers are shown in their depressed position and the lower wall 87 of each of the openings in the looped portions of the plungers 83 is in that position concentric with the shaft 85 so that ever one of said plungers has this lower wall engaged by the spiral rib 86 which positively holds the plungers down. The plunger at the extreme right of the series has in this position of the parts its wall 87 engaged by the rib 86 at the extreme rear end of said wall and the plunger at the left of the system has its wall 87 engaged by said rib at the front end of its wall, and intermediate plungers have their walls 87 engaged by said rib at intermediate points. This concentric wall of the plunger opening is, however, engaged by said rib in every one of the plungeis so that they are all held down. If the shaft 85 be rotated clockwise in Fig. 1 the plunger at the extreme left will be elevated almost immediately by the engagement of the spiral with the upper wall 88 of the opening in said plunger. The next plunger will remain in its lower position until the spiral reaches the point where the forward end of the wall 87 joins the forward end of the wall 88 whereupon the second plunger will be elevated, and so on across the series. The shaft is so moved prior to a registering operation. At the end of such operation and before moving the frame 45 to its upper disconnecting position the shaft is rotated back counter-clockwise to its Fig. 1 position. In this rotation the right-hand plunger will be operated first, the second one thereafter, and so on, throughout the series. The upper wall 88 of the opening in each plunger is made in the arc of a circle, which circle is concentric with the shaft 85 when the plunger is in its upper position. In short, the centers of the two arcs 87 and 88 are apart a distance about equal to the extent of mois rotated back to registering mechanism tion of the plunger. It will be perceived that when the-shaft first begins to rotate the plunger at the end of the series will immediately be moved upward to the extent of .its motion until the center of the are 88 reaches the center of the shaft 85 after which further rotation of the shaft has no further effect on that plunger. At this instant the next'plunger begins to more and after it the'next,,and so on; and the same thing occurs in opposite order when the shaft is rotated in the-opposite direction. The rear wall of the opening in each plunger may be made a straight line as shown in Fig. 1.

In operation the shaft. $5 and plunger-s 83 normally occupy the position shown in Fig; I where all of the gears in the register frame 45 are positively locked in proper position, and it remains in this position until theflframe 45 is turned down to its connecting position. The shaft is rotated clockwise to elevate all of the plungers preliminary t a regist ring operation audit its normal position before raising' ithe' frame 45' toits disconnecting position. This may be done by any suitable means, 'and "n the simplified actuating mechanism shown, a hand crank 89 is pro- 3 ,vi :ledonthe end ofthe' shaft for this purf pose.
